Description

Role of HAK gene in regulation and control of plant traits

Technical Field

The invention relates to the field of biology, in particular to the field of plant biology, and specifically relates to an effect of a HAK gene in regulation and control of plant traits.

Background

The prior art reports that the KUP/HAK/KT family is the potassium transport family which is first discovered, has the largest number and most abundant functions in the biology world and is widely present in a plurality of species. It mediates the potassium absorption of plant in low potassium stress, and participates in the physiological process of plant cell enlargement, root auxin transport and the like, the expression of the family gene is regulated and controlled by the factors of plant growth and development regulating factors, environmental stimulation and the like, and participates in the growth and development and stress response mechanism of the plant. KUP (K + uptake permenase) is firstly found in Escherichia coli and is responsible for coding Escherichia coli potassium absorption permease; HAK (high-affinity K +) is a KUP homologous gene identified in Schwanniomyces. KT (K + transporter) is a transporter with a potassium transport function found in arabidopsis thaliana.

Salt stress is one of the major abiotic stresses of plants, and causes changes in a plurality of metabolic pathways of the plants, thereby generating complex physiological level changes, mainly manifested as ion imbalance, water deficiency and oxidative toxicity, and further causing reduction of plant photosynthesis, increase of energy consumption, acceleration of senescence, limitation of growth, reduction of yield and quality. One of the main ways plants increase their own salt stress resistance is to regulate potassium (K) and sodium (Na) transport in vivo through xylem parenchyma. The tolerance to salt stress is realized by the adaptation to the toxic action of Na + and the maintenance of K + nutrition, and the plant with higher K +/Na + ratio has stronger tolerance to salt stress.

Research reports that KUP/HAK/KT family genes are also induced by high-salt adversity stress, however, at present, the genes exerting salt resistance in a plurality of HAK subtypes and the mechanism thereof are not clear.

Therefore, there is a strong need in the art to resolve the mechanism of action of the relevant genes and to develop a method capable of enhancing the tolerance of plants to high salt stress.

Detailed Description

The present inventors have extensively and intensively studied and, after extensive screening, have for the first time unexpectedly found that a HAK gene of a plant (such as tomato) or a protein encoded by the gene or a promoter thereof can be used for controlling plant traits, including: root length, root weight, root branching, plant height, salt tolerance. Research has shown that overexpression of the HAK protein (transporter) or its encoding gene in tomato increases the salt resistance of plants. The HAK protein and the encoding gene can be used for regulating and controlling the Na + transport of plants, and under the condition of salt stress, the HAK protein can be used for regulating and controlling the loading and unloading of Na + in the plants so as to improve the salt tolerance of the plants. Specifically, the HAK protein enhances Na + transport to and from the xylem in plants, while facilitating Na + transport from the root to other tissues or the outside world.

Furthermore, the present inventors have also surprisingly found that when the amino acid sequence of the HAK protein is subjected to C-terminal deletion by gene editing techniques, under salt stress, root length and root branching can be increased, plant height of a plant can be increased, and salt tolerance of the plant can be enhanced. The improvement of the root can enhance the lodging resistance of the plant, promote the absorption of nutrient substances and enhance the environmental adaptability. And the increase of the plant height can increase the biomass and/or the yield of the plant.

The research also finds that the deletion of 6 bases at the downstream 48bp of the HAK gene promoter and the replacement of the base G to A at 3093bp cause the reduction of the salt tolerance of the plant.

On the basis of this, the present invention has been completed.

HAK protein and encoding nucleic acid sequence

As used herein, the terms "HAK protein", "HAK polypeptide", "HAK transporter" are used interchangeably and refer to a class of ion transporters that are present on different organelle membranes, such as the plasma membrane, the vacuolar membrane, and the thylakoid membrane.

As used herein, the terms "mutant HAK protein", and "mutant HAK protein" are used interchangeably and refer to a mutant obtained by mutation of the amino acid sequence of a wild-type HAK protein.

As used herein, the terms "HAK gene of the present invention", "HAK gene", "nucleic acid sequence encoding HAK protein", which are used interchangeably under appropriate conditions, all refer to DNA sequences, all refer to HAK genes or variants thereof derived from plants (e.g., tomato, wheat, etc.).

In a preferred embodiment, the HAK gene of the invention is SlHAK20 gene, the nucleotide sequence of which is shown in SEQ ID NO. 1, and the coded amino acid sequence of which is shown in SEQ ID NO. 2.

The invention also includes nucleic acids having at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 85%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98% or at least 99% sequence homology to a preferred gene sequence of the invention (SEQ ID NO: 1), which nucleic acids are also effective in modulating an agronomic trait in a plant, such as tomato.

"homology" or "identity" refers to the match of sequences between two polypeptides or between two nucleic acids. When a position in both of the sequences being compared is occupied by the same base or amino acid monomer subunit (e.g., a position in each of two DNA molecules is occupied by adenine, or a position in each of two polypeptides is occupied by lysine), then the molecules are identical at that position. The "percent identity" between two sequences is a function of the number of positions compared at the first by the number of matching positions shared by the two sequences x 100. For example, if 6 of 10 positions of two sequences match, then the two sequences have 60% identity. Typically, the comparison is made when it is difficult to Align the two sequences to produce maximum identity, such alignment can be conveniently performed by using, for example, a computer program such as the Align program (DNAstar, inc.) Needleman et al (1970) j.mol.biol.j.mol.mol.biol.j.mol.biol.j.mol.j.mol.biol.48: 443-453. The algorithm of e.meyers and w.miller (comput.appl biosci.,4, 11-17 (1988)) which has been incorporated into the ALIGN program (version 2.0) can also be used to determine percent identity between two amino acid sequences using a PAM120 weight residue table (weight residue table), a gap length penalty of 12, and a gap penalty of 4. The method is realized. Furthermore, percent identity between two amino acid sequences can be determined using the Needleman and Wunsch (J MoI biol.48:444-453 (1970)) algorithms that have been incorporated into the GAP program of the GCG software package (available at www.gcg.com), using either the Blossum 62 matrix or the PAM250 matrix, and GAP weights (GAP weights) of 16, 14, 12, 10, 8, 6, or 4, and length weights of 1, 2, 3, 4, 5, or 6. In this context, variants of the genes can be obtained by insertion or deletion of regulatory regions, random or site-directed mutagenesis, and the like.

In the present invention, the nucleotide sequence of SEQ ID NO. 1 may be substituted, deleted or added with one or more nucleotides to generate a derivative sequence of SEQ ID NO. 1, and due to the degeneracy of codons, even if the homology with SEQ ID NO. 1 is low, the amino acid sequence shown as SEQ ID NO. 2 can be basically encoded. In addition, the meaning of "a nucleotide sequence in SEQ ID NO. 1 is substituted, deleted or added with at least one nucleotide-derived sequence" also includes a nucleotide sequence that hybridizes to the nucleotide sequence shown in SEQ ID NO. 1 under moderate stringency conditions, more preferably under high stringency conditions. These variants include (but are not limited to): deletion, insertion and/or substitution of several (usually 1 to 90, preferably 1 to 60, more preferably 1 to 20, most preferably 1 to 10) nucleotides, and addition of several (usually less than 60, preferably less than 30, more preferably less than 10, most preferably less than 5) nucleotides at the 5 'and/or 3' end.

It is to be understood that although the genes provided in the examples of the present invention are derived from tomato, the gene sequences of HAK derived from other similar plants (especially plants belonging to the same family or genus as tomato) and having a certain homology (conservation) with the sequence of the present invention (preferably, the sequence shown in SEQ ID NO: 1) are also included in the scope of the present invention, as long as the sequence can be easily isolated from other plants by those skilled in the art based on the information provided in the present application after reading the present application.

The polynucleotide or nucleic acid sequence of the present invention may be in the form of DNA or RNA. The DNA forms include: DNA, genomic DNA or synthetic DNA, DNA may be single-stranded or double-stranded. The DNA may be the coding strand or the non-coding strand. The sequence of the coding region encoding the mature polypeptide may be identical to the sequence of the coding region shown in SEQ ID NO. 1 or may be a degenerate variant.

Polynucleotides encoding a mature polypeptide include coding sequences that encode only a mature polypeptide; the coding sequence for the mature polypeptide and various additional coding sequences; the coding sequence (and optionally additional coding sequences) for the mature polypeptide as well as non-coding sequences.

The term "polynucleotide encoding a polypeptide" may include a polynucleotide encoding the polypeptide, and may also include additional coding and/or non-coding sequences. The invention also relates to variants of the above polynucleotides which encode fragments, analogs and derivatives of the polyglycosides or polypeptides having the same amino acid sequence as the invention. The variant of the polynucleotide may be a naturally occurring allelic variant or a non-naturally occurring variant. These nucleotide variants include substitution variants, deletion variants and insertion variants. As is known in the art, an allelic variant is a substitution form of a polynucleotide, which may be a substitution, deletion, or insertion of one or more nucleotides, without substantially changing the function of the encoded polypeptide.

The present invention also relates to polynucleotides which hybridize to the sequences described above and which have at least 50%, preferably at least 70%, and more preferably at least 80% identity between the two sequences. The present invention particularly relates to polynucleotides which hybridize under stringent conditions to the polynucleotides of the invention. In the present invention, "stringent conditions" mean: (1) Hybridization and elution at lower ionic strength and higher temperature, e.g., 0.2 XSSC, 0.1% SDS,60 ℃; or (2) adding denaturant during hybridization, such as 50% (v/v) methylphthalamide, 0.1% calf serum/0.1% Ficoll,42 deg.C, etc.; or (3) hybridization only when the identity between two sequences is at least 90% or more, preferably 95% or more.

It is to be understood that although the HAK gene of the invention is preferably from tomato, other genes from other plants that have some homology and function in close proximity to the tomato HAK gene are also within the contemplation of the invention. Methods and means for aligning sequence identity are also well known in the art, for example BLAST.

For example, in another preferred embodiment of the present invention, the HAK gene of the present invention may also be OsHAK4 gene derived from rice, the nucleotide sequence of which is shown in SEQ ID NO. 3, and the amino acid sequence of the encoded protein of which is shown in SEQ ID NO. 4.

The full-length sequence of the HAK nucleotide or a fragment thereof of the present invention can be obtained by a PCR amplification method, a recombination method, or an artificial synthesis method. For PCR amplification, primers can be designed based on the nucleotide sequences disclosed herein, particularly open reading frame sequences, and amplified using commercially available DNA libraries or cDNA libraries prepared by conventional methods known to those skilled in the art as templates to obtain the sequences. When the sequence is long, it is often necessary to perform two or more PCR amplifications, and then splice together the amplified fragments in the correct order. Once the sequence of interest has been obtained, it can be obtained in large quantities by recombinant methods. Usually, it is cloned into a vector, transferred into a cell, and then isolated from the propagated host cell by a conventional method to obtain the relevant sequence.

In addition, the sequence can be synthesized by artificial synthesis, especially when the fragment length is short. Typically, long fragments are obtained by first synthesizing a plurality of small fragments and then ligating them together. At present, DNA sequences encoding the proteins of the present invention (or fragments or derivatives thereof) have been obtained completely by chemical synthesis. The DNA sequence may then be introduced into various existing DNA molecules (or vectors, for example) and cells known in the art. Furthermore, mutations can also be introduced into the protein sequences of the invention by chemical synthesis.

The function of the SlHAK20 gene is closely related to the transport of Na + ions in a plant body, and the SlHAK20 gene can regulate the accumulation of Na + ions at the root of the plant, promote the transport of Na + from the root to xylem and unload Na + from xylem to root parts, thereby reducing the Na +/K + ratio of the root and the above-ground parts and enhancing the salt resistance of the plant.

Example 3: HAK20 mutation improves effects on plant root development, plant height and salt resistance

In this experimental example, mutants of the slhak20 gene, slhak20-3 and slhak20-4, in tomato TS-21 variety were generated by a gene editing method. The amino acid sequences of slhak20-3 and slhak20-4 are shown in SEQ ID NO. 12 and SEQ ID NO. 14, respectively.

1. Construction of CRISPR editing tools

A Single guide RNA 5'GGTCTCCTATCATGGGTGCATGG 3' upstream primer and a Single guide RNA downstream 3093bp from SlHAK20 genome ATG were designed, and GATTG and AAAC.. C linkers were added to the primers and synthesized (Thermo Fisher Scientific), and the primers were diluted to a final concentration of 10. Mu.M, and 10. Mu.L of each was mixed. Annealing in a PCR instrument (BioRAD) to form double chains, directly carrying out enzyme digestion on the double chains and Bsa I-HF (New England Biolabs) of a target vector pCAMBIA1300-Cas9, carrying out T4 chaining for 2h, carrying out kanamycin screening to obtain a correct recombinant binary vector after a reaction product is transformed into escherichia coli DH5 alpha competence, carrying out colony PCR identification by using M13F and sgRNA downstream primers, carrying out Sanger sequencing on a PCR product, and transforming the tomato by using an agrobacterium-mediated callus floral dip transformation method for subsequent experiments.

2. Genetic transformation

Is realized by utilizing agrobacterium-mediated callus infection. The agrobacterium carrying the target vector is incubated with the detoxified tomato cotyledons for 20min for infection, after the agrobacterium is abandoned, the tomato cotyledons are placed in a co-culture medium (components 4.3g/L MS salt (519), 1mg/L IAA,0.3mg/L ZT,30g/L sucrose,7.4g/L agar, pH 5.5-5.6) for dark culture for 2-3 days. The co-cultured tomato cotyledons were transferred to a selection medium containing 6mg/L of Hygromycin and 300mg/L of Timentin antibiotic (the composition was the same as the co-culture medium) for 7-10 days of selection subculture each generation until tissue culture seedlings were differentiated. The tissue culture seedlings are cut down and inserted into a rooting culture medium (components of 4.3g/L MS salt (524), 20g/L sucrose,300mg/L Timentin,7.4g/L Agar, pH 5.7-5.8) for rooting, and the seedlings can be acclimatized and transplanted after the root systems develop to be strong.

3. Plant culture and mutant screening

Taking the rooted tissue culture seedling leaves, extracting total DNA, carrying out PCR amplification through an upstream primer at about 300bp of the sgRNA upstream and a downstream primer at 300bp of the sgRNA downstream to obtain a target strip, carrying out Sanger sequencing on the target strip, comparing the sequencing result with a reference genome sequence of SlHAK20 to obtain a gene editing result, transplanting the homozygous positive seedlings into peat soil, and culturing and expanding the propagated seeds for subsequent tests.

4. Identification of phenotype (root development, plant height, sodium and potassium ion content)

And (3) disinfecting the gene editing homozygote and the corresponding wild seeds for 20min by using 10% sodium hypochlorite, then finally placing the seeds in a 1/4MS culture medium horizontally, transferring the seeds after germination, vertically placing the seeds in a 1/4MS culture medium containing 200mM NaCl, and culturing for 1 week or 1 month, and then counting the characters such as fresh weight and the like. The control group was cultured in 1/4MS medium without NaCl for 10 days while standing upright.

Or transferring the germinated seedlings to a 1/4MS culture medium for about 10 days in a vertical culture. The seedlings were transplanted into soil blocks or liquid culture boxes (1/4 MS liquid medium), and after further 18 days of culture, 200mM NaCl was added to the culture solution or the tomatoes cultured in the soil blocks were watered with water containing 200mM NaCl. After 2-3 weeks of salt treatment, rehydration is carried out, namely the characters such as plant height and the like are counted after 2 weeks of culture solution or water culture without NaCl and tomato irrigation. The control group was cultured with NaCl-free 1/4MS medium or water-irrigated soil blocks for 30 days and then the plant heights were counted.

5. Determination of sodium and potassium content

6. Results and analysis of the experiments

(1) SlHAK20 mutation can affect the development of plant roots

As shown in FIG. 10, the mutant slhak20-3, slhak20-4 had increased root length and increased number of root branches compared to wild-type after salt treatment.

(2) Influence of SlHAK20 mutation on plant height and biomass

As shown in FIG. 11, the mutant slhak20-3, slhak20-4 increased in plant height compared to the wild type after salt treatment.

(3) Influence of SlHAK20 mutation on sodium ion and potassium ion content of plants

As shown in FIG. 12a, in salt stress conditions, na +/K + of mutant slhak20-3, slhak20-4 was significantly reduced compared to wild type roots.

As shown in FIG. 12b, under salt stress conditions, the Na +/K + of mutant slhak20-3 and slhak20-4 was significantly reduced compared to wild-type aerial parts.

7. Conclusion of the experiment

The experimental result shows that the root length and the plant height of the SlHAK20 large-fragment deletion mutant are obviously superior to those of a wild type under salt stress, so that the biomass of the plant can be increased, and even the yield of the plant is isophenotypic; the Na +/K + ratio of plant tissues can be reduced, so that the salt resistance of plants is enhanced.

As can be seen from the analysis of the amino acid sequences of slhak20-3 and slhak20-4 (SEQ ID NO:12 and SEQ ID NO: 14), the N-terminal positions 1-240 of these two mutants are completely identical; the amino acid sequence of slhak20-3 further includes the sequence HGLLPLLSLGYTVS at the C-terminus; the amino acid sequence of slh ak20-4 also includes C-terminal CMDSYHSSHWDIQYHKALSEHI sequence. This is because the nucleic acid sequence after the coding amino acids 1 to 240 undergoes frame shift mutation and terminates prematurely during gene editing, resulting in the amino acid sequence after positions 1 to 240 not being identical to the wild type.

Both SlHAK20-3 and SlHAK20-4 can improve salt resistance of plants, and the same amino acid region (1-240 sites at the N terminal) of the SlHAK20 and the SlHAK has a deletion of 473 amino acids at the C terminal compared with the wild type SlHAK 20. In other words, the SlHAK20 protein with 473 amino acids deleted from the C-terminal can be considered to have an important effect on enhancing the salt resistance of plants.

We over-express the amino acid sequences of slhak20-3 and slhak20-4 in rice and maize, which can also enhance the salt resistance of plants.

The research result has application value for improving the characters, can realize the regulation and control of the characters such as salt resistance and the like by improving the HAK gene of the plant, and has important scientific value for cultivating new stress-tolerant plant varieties.
